PATROL. Volume 1. Model Description and Analysts's Guide
Abstract
A mathematical model of a Coast Guard cutter on a law enforcement patrol is described in this report. The kernel of the model is a Markov process that uses the phases of the patrol, such as search or transit, as states of the system. The phases of the patrol are separated by events, such as a detection which terminates a search and potentially initiates the pursuit of a vessel. A computer program called PATROL implements the model described here. The information that describes the law enforcement patrol is organized into four categories: Cutter, Traffic, Area, and Choices. Model outputs are grouped under three headings: Allocation of Effort, Vessel Performance, and Logistics. Distance, time, and fuel consumption information for every component of the patrol can be printed out at the option of the user. PATROL has a range of potential uses. These include vessel assessment, scenario development, accessing policy, strategy and tactics, and understanding the interrelationships of the different parts of the patrol problem. The appendices of this report include detailed calculations of the probability of detection and interception algorithms used in the model to calculate the time between detections and the time to intercept. This is one volume of a three volume set that describes PATROL. Volume II is a user's manual for the model. Volume III includes all of the programmer level documentation necessary to maintain the model.
